IMPORTANT SAFETY INFORMATION (continued)
Protect from becoming dry
If the membrane dries out, irreversible damage to the Ultra
Filter membrane may result. Protect the filter from becoming
dry by keeping it wet and sealed at all times.
Protect from freezing
If the Ultra Filter membrane freezes during operation or stor-
age, irreversible damage to the membrane and brittle cracking
of the cartridge or housing may result.
Protect from direct sunlight or other UV sources
Avoid long-term exposure to direct sunlight or other UV
sources. The Ultra Filter should be stored in a dark location.
Protect from high temperatures or abrupt variation in
temperature
The maximum operating temperature is 104°F (40°C). Avoid
abrupt variations in temperature. Any temperature variation
should be made slowly.
Protect from rough handling or dropping
Mechanical damage, external breakage, and/or internal break-
age of the filter can result if the system is dropped or bumped.
Handle with care at all times during transportation and instal-
lation.
Protect from organic solvents and concentrated acids
Prevent any and all contact of the membrane with strong sol-
vents, solvents containing chlorine, or concentrated acids. Do
NOT use strong solvents or concentrated acids on any plastic
parts of the filter system. Examples of some solvents to avoid:
acetone, methyl acetate (nail polish remover); hexane (spot
removers); turpentine, toluene (paint thinners); dry cleaning
solutions, insecticides.
Protect from abrasive material
The membranes must be protected from abrasive materials
like shavings left in a pipe. Abrasive materials in contact with
the membrane can cause irreversible damage to the mem-
brane. All pipes must be flushed clean before installing the fil-
ter. All plastic parts of the filter system must be protected from
sharp objects like knives, sand paper, or other tools. Cutting
or nicking a plastic part can weaken it and cause a leak. Do
NOT use abrasive cleansers on any plastic parts.
Protect from water hammer
The system must be protected from shock, pressure surges,
or pulsation that may occur inside water pipes. Water ham-
mer occurs in pipes when a valve or faucet shuts quickly.
Install a water hammer arrestor (pressure vessel containing
compressed air separated from the water by a diaphragm) to
reduce pressure shock.
P/N 1011103 Rev. E 05/13
This equipment is to be installed to comply with the
basic plumbing code of the Building Officials and Code
Administrators, Inc. (BOCA) and the Food Service
Sanitation Manual of the Food and Drug Administration
(FDA).
Water Flow Regulator Assemblies are NOT interchange-
able. Operating the system with the wrong Water Flow
Regulator or without a regulator can damage the sys-
tem, cause personal injury, and voids the warranty!
All electrical connections must be in accordance with
local electrical codes and any other applicable codes.
A ground fault circuit interrupter (GFCI) must be
installed on the circuit to this system.
When installed on metallic plumbing, a properly sized
electrical bonding jumper must be installed across the
inlet and outlet pipes serving this unit.
